STEERING-GEAR ATTACHMENT.

Specification of Letters Patent. Patented S t. 1921 7 Application filed J'u1y 2, 1920. Serial No. 393,582;

to the central position which it occupies when the steering wheels are 1n the posltion to cause the straight ahead travel of the vehicle.

The object of the inventlon is to rovlde such an attachment in an easlly applled .and

' comparatively cheap'but exceeding efficient form. 7 a

The invention consists in the constructlon and combination of parts shown in the drawing, hereinafter described and pointed out definitely in the appended clalms.

In the drawings, Figure 1 is a plan v1ew showing the. invention applied to the steering post of a motor Vehicle. Fig. 2 1s a front elevation, and Fig. 3 1s a side elevation of said invention. p

Referring to theparts by reference characters, 10 represents the rotatable steering post of a motor vehicle. Attached to it at a convenientpoint, preferably near its lower end, is a gear 12. A rackbar 15 is slidably mounted in two brackets 16 which maybe attached to any suitable fixture, such for" example, as the transmission gear case (indicated by dotted lines in Figs. 2 and 3),

and in such position thatit always holds the rack bar in engagement with the gear 12.

- The rack bar projects at'both ends beyond the brackets, and each of these projecting ends is surrounded'by a compressed coil spring 17 which thrusts against the ad acent bracket and againsta thrust collar which is adjustably secured to the end of said rack bar. The ends of the rack bar are threaded and on each a nut 18Yis screwed and serves as the thrust collar for engagement with the end of a sprin 17. As these nuts are screwed on or o the tension of the springs will be varied, and so regulated that the two springs will be in balance when the rack' bar is in the position it must occupy, when the steering post is in that position which it must occupy, when the steering wheels are set to steer the vehicle in a straight path.

' Having described my invention, I claim 1. The combination with the rotatable steering post of a motor vehicle, of a gear secured thereto, a rack bar mounted to slide endwise in engagement with said gear, and opposed springs acting on, said rack bar to move it endwise and return it tothe position in which the springs balance each other.

2. The combination with the rotatable steering post of a motor vehicle, of a gear fixedthereto, two uide brackets fixed on opposite sides of said steering post, a rack bar slidably mountedlin said brackets in engagement with said gear, a thrust collar adjustably secured to each end of said rack bar, and balanced coil springs surrounding the rack bar and compressed between said brackets and thrust collars.

3. The combination with a steering post of a motor vehicle, of a gear secured thereto, a rack bar mounted to slide endwise'in engagement with said gear, and an elastic mechanism. acting on said rack bar adapted to flexibly resist the steering efl'ort used on said post and to return said post to a straight aheadposition when released.

In testimony whereof, I hereunto aifix my signature. I
